摘要
为了顺应国家发展需求,对锌资源的不断开发使高品位矿石日益枯竭,并产生了大量的含锌冶炼渣,且由于锌的生产方式多样,含锌冶炼渣成分及性质各不相同,后续的处理难度也显著提升。含锌冶炼渣的大量堆存不仅会对周围环境造成严重危害,还会导致有价金属资源浪费。本文总结了含锌冶炼渣的危害及现行的利用方式,并着重介绍了回收含锌冶炼渣中有价金属的主要处理工艺的原理、优缺点及研究现状。最后指出了含锌冶炼渣资源化处理技术可加强的研究方向。
In order to meet the needs of the national development,the continuous development of zinc resources has increasingly depleted high-grade ore and produced a large amount of zinc smelting slag.Due to the diverse production methods of zinc,the composition and properties of zinc smelting slag are different.The processing difficulty is also significantly increased.Storage of zinc smelting slag will not only cause serious harm to the surrounding environment,but also cause waste of valuable metal resources.This article summarizes the harm of zinc smelting slag and the current utilization methods,and focuses on the principle advantages and disadvantages and research status of the main treatment processes for recovering valuable metals from zinc smelting slag.Finally,it points out the research direction that can be strengthened in the resource treatment technology of zinc smelting slag.
